I may be mistaken, but I could have sworn that using the oiled filters leads to premature fouling of the intake sensor? No? Even my local tuner advised against any oiled air filters and said to stick with paper.

Yea..the MAF and also silicon (dirt) will be higher when you do a used oil analysis. I wouldn't touch one of these with a 10 foot pole.....That's just me though.

I had a K&N in my old car, and was actually amazed with how much grime and dirt built up around the throttle body whereas it was squeakily clean thousands of miles prior. That was one of the reasons why I was reluctant to put one in my Foz.
